The popular, once bipartisan idea to hold down Medicare costs is now at the center of President Joe Biden's domestic agenda. Legislation backed by the administration calls for Medicare to mirror other government agencies, such as the Department of Veterans Affairs, in being able to negotiate for cheaper medicine through the Part D program. The idea could potentially save the government nearly $500 billion over a decade. The drug pricing proposal could also translate to lower prescription costs across the board. The drug industry, according to its top lobbyist, Stephen Ubl, has made defeating the provision its top priority. Inside the Beltway, the opposition is coming from familiar faces. Many leading Democratic lawmakers and staff have been hired by the drug industry to convince their former colleagues to abandon the drug pricing proposal. Pfizer alone has assembled a lobbying team that includes Dean Aguillen, a former adviser to House Speaker Nancy Pelosi, D-Calif.; Remy Brim, a former health policy adviser to Sen. Elizabeth Warren, D-Mass.; and over half a dozen aides to senior Senate Democrats. Ann Jablon, former chief of staff to Rep. Richard Neal, D-Mass. ... currently represents several drug companies as a lobbyist, including Amgen Inc., Astellas Pharma, and Bayer. Pharmaceutical Research and Manufacturers of America, the trade group that represents the largest drug companies in the world, has also gone on a hiring spree of Democratic lobbyists.
